Kanal (1957) on Netflix

In 1944, during the Warsaw uprising against the Nazis, Polish Lieutenant Zadra and his resistance fighters use Warsaw's sewer system to escape the German encirclement.

A symbolic depiction of hell on Earth, set in the last days of the Warsaw uprising in 1944. Lieutenant Zadra is commanding a company of 43 men in a desperate battle amidst the ruins. Facing German offense and cut off from their comrades, Zadra is commanded to retreat his men through the sewer system ('kanal'). Zadra and his men are reluctant to do so, as it would indicate that they have lost the battle, but decide to obey the orders. However, as the men (and women) retreat, it becomes clear that their desperate attempt to flee from the hell of battle will result only in more death and suffering...

September, 1944. It's the 56th day of Warsaw's uprising against the Nazis. The third Platoon of the Resistance is down to 43 heroic men and women, and they're penned in. After a last day of fighting, and of good-byes to family, to love making, and to music, a handful of doomed survivors wade into the city's underground sewers in hopes of escape. Their valor is tested a final time.
